Much of the cannabis grown in the US these days is done so in small indoor gardens. They are properly termed "stealth grows" or "microstealth grows" depending on how large or small the operation. These are very hard for LEO (law enforcement officers) to find due to the small electricity consumption and heat signature. Most are under 1000 Watts total lights and fans, about the same as a common pc, and are located in a vented interior closet. Cervantes assures us that a decent cannabis gardener can achieve a 2 gram per light Watt yield, though most average about 1/2 that.
Many micro growers have tried LED systems, several of which are sold to cannabis growers to cut heat and electric footprint. Thus far the results have been extremely poor both in quantity and in quality. The standard for lighting is High Intensity Discharge (HID) lighting - Metal Halide (MH) and High Pressure Sodium (HPS) bulbs. Currently available ballasts can switch from one type to another automatically and consume much less electricity than electromagnetic ballasts. Lower budget growers use compact fluorescent lighting (CF's) to good effect and yield. There is usually some "overgrow" beyond the growers needs that the gardener passes on or sells to other consumers.
Many street lights are 1000 Watt HPS bulbs, commercial buildings use 1000 W HPS and MH bulbs as well so these are available at Home Depot etc as well as hydro stores everywhere.
No matter what laws you write, no matter how much money you waste on futile attempts to enforce those laws, the very act of writing and attempting enforcement of "drug" laws escalates the value of the substance in question. In my lifetime I have seen the price of an ounce of cannabis go from $10 US (Acapulco Gold, 1967) to $750 US (Canadian hydroponic AK 47, 2011) mostly due to prohibition, which is indeed the US federal governments attempt to repeal the law of supply and demand. The potential profits in the illicit substance market insure the involvement of organized crime in same. A good perspective on this aspect of the topic can be found in "Why Our Drug Laws Have Failed and What We Can Do About It" by CA Republican Superior Court Justice (and former federal drug war prosecutor) Grey. If you can be arsed to read it, you will be enlightened.
It is not possible for the government to regulate what individual persons consume for whatever purpose. It is no business of the government what the persons motivation is. The money spent on interdiction jurisdiction and incarceration of persons for "drug crimes" are assets that are not available to fight terrorism, violent crimes and serious economic crimes.
You want to "go green"? Buy cf's, install roof mounted solar and wind generators, drive an efficient auto that matches your lifestyle needs and drive it wisely. Improve your homes insulation, upgrade your heating and cooling systems, buy organic produce grown locally.
Want to get pot growers to grow greener? Support legalization of all drugs, starting with cannabis. "Drugs" - whatever those may be defined as - should be handled as a health care issue, not a legal issue. The current system simply does not work at all.
You will note the correction on your perspective, Cosmic. It is illogical to equate violent crimes against others with consuming psychotropic substances. That is a "straw man" argument and must be tossed as such.I do perceive and appreciate your emotional investment in this topic however.
Shit Dude ? You want to talk about propagating too . O.K. Stoni is the Man . He hit it nail on fish whacked . Scare crows on the run way .
That is how they do it . Halogens work great but ventilation is very important . I heard of peoples putting oxygen bottles in the rooms too. To lift fresh air levels . White flys got to be managed that is for sure , so count on some type of pesticide. Lets hope it is not D.D.T.
O.K. legalize is the correct answer for any sane person
